I have a knocking from the right side clutch cover. I made sure valves and cam chain were adjusted. Is this a rod knock? Having trouble uploading the video. Running 15w oil right now. What could it be? Thanks

Just got this cafe racer together and running. There was a metal on metal noise coming from the tappet. I found the nut and adjuster worked it's way off the lifter. The nut is missing though. My question is, is it in the head somewhere or could it have possibly fallen past a valve into the...

Just timed my pamco and adjusted valves. My advance springs back like it should, but my throttle hangs only when I rev it up and hold the rpms up. It doesn't hang if I just blip the throttle quick. It drops nice and quick. What is this indicative of? Jetting or needle position in the carb? I...

I just got another XS, this time already built! I got it running good. Then I decided to move the coil and capacitor under the seat and clean up some wiring. It is now really hard to start and when it does, only fires on the left cylinder. Bike is simplified wiring and kick only. PAMCO/PMA. I'm...

Hi, I recently bought a project cafe XS650 (this is my 4th XS650). I am in the process of wiring it enough to get it started and then I will strip it down for frame and engine paint. Anyway, I believe the Pamco electronic advance box that came with the bike is bad. Everything was brand new with...

I did search what I could, but couldn't find anything specific to a R/R with PMA setup with 6 wires. The bike was previously wired, but I am not sure if it was ever on the road or done correctly. The RR has 3 yellow, black, red and green. OK, I believe the PMA tests good. I have 21 VAC from...

Hello, I am working on a chopper basket case for my brother. Everything should be ready to go now except the carb situation. I have two sets of BS-38s. A 584 (earlier style) and 2F0 (newer style). I plan on combining these two sets for reasons that would take too long to explain, but I had some...

Can anyone confirm what metal the foot shift lever is made from? I have an extra billet aluminum one from a dirt bike I would like to weld the splined end of a stock XS shifter on, but I am not sure what the stock one is. It seems like steel. Thanks.

1978 XS650, Really short dual exhaust, Mike's POD filters, BS 38 carbs, stock ignition/points/advance. Hey guys!, I got my chopper project running, charging and riding, so I took it to a buddy's shop for them to check the timing with a light (bc I don't have one) and jet the carbs. They...

I bought a non running project bike that is now running but not charging. The rotor tested bad at 2.3 ohms so I replaced it with a good used one. The bike is a 1978 running points, so I bought a rotor for the early model bikes. I put in on and there was no change. No results on the slap test and...

I feel like my 81 Café build is down on power after riding my buddies the other day. Granted, mine will do 80mph, but I have a feeling a correct running XS650 should do better then that. My bike is all stock, except with a shortened 2 into 1 exhaust and pod filters. What's the best bang for the...

I wanted to get the bike ridable this weekend for the first time. After getting a fresh battery i fired the bike up and checked to see if it was charging. It was not. So i did some quick testing and found the resistance between rotor rings to be around 3 ohms after subtracting lead resistance...

Are the stock breathers supposed to have a screw and a plug like this? I just got the bike running and i had a lot of pressure wheni would unscrew the dipstick. I found this when i took apart the breather: Posted via Mobile

Background: I am not good with electrical stuff. Its a 1978 with points and original coils. Bought the bike with the advance rod, points, weights etc in a box. Not running do to being an unfinished project. I finally got all the small missing pieces and attempted to assemble everything last...

I bought a bike and is missing the top hat piece, p/n 90387-20166-00. I can't find one on the internet anywhere, does anyone have one they will sell or know where I could get one? thanks!!

These are 35mm from a '78. I bought them not knowing they were extended. The measure 35" top to bottom on the bike so im pretty sure they are 6" longer then stock. Pm with offers, i need stock or lowered ones. Fresh gloss black paint and fresh 20w fluid, do not seem to leak at all. They are not...

Anyone have a full set of 35mm forks that are already dropped 2" or so? Thanks!

My brother has an 81 with electronic ignition. The right side of the motor has no advance weights, just a nut on the rod. This picture is the left side of the motor. This isnt a pamco brand is it? I am curious because i have an 81 i have a pamco for, but it was my understanding i would still...

My motor and vin dont match- no big deal. The frame and title are good. Frame and title starts with 2f0 and the title says 1978, so that makes sense, but the engine says 4n9-, which says 1981 when i looked it up. Im really confused because it is a points motor with two coils and all. Is it...

Hi! I am new to the site. I bought a 78 bobber project and am trying to fit up a front brake setup. The forks arent correct for the caliper bracket i have. Can anyone confirm wha year these are? Thanks!
